- 摘要:
- 以重庆市璧山县大路镇综合国土整治规划(2008-2020)为研究对象，从农用地、建设用地、未利用地三大地类出发，构建了综合国土整治规划区环境友好型土地利用评价指标体系并实证评价了综合国土整治规划对环境友好型土地利用的影响。研究表明：(1) 构建的环境友好型土地利用评价指标体系，基本可以较完整地表征综合整治前后规划区环境友好型土地利用的状态和水平。(2) 整治后规划区三大地类的土地利用环境友好评价指数都将得到提高。2008-2020年，农用地利用环境友好综合指数将从0.191 6上升到0.247 0，建设用地利用环境友好综合指数将从0.265 3上升到0.443 3，未利用地利用环境友好综合指数将从0.042 2上升到0.086 6。(3) 规划区综合国土整治后土地利用环境友好综合评价指数将从2008年的0.498 9预计达到2020年的0.776 8，增幅为55.7%，土地利用环境友好状态将从整治前的较低状态上升到整治后的较高状态。由此可见，综合国土整治是提高区域土地利用环境友好状况的重要途径，符合土地合理利用和土地可持续的理念。
- Abstract:
- This paper took comprehensive land improvement planning of Dalu Town, Bishan County of Chongqing City, from 2008 to 2020 as an object, built environment-friendly land use evaluation system, and analyzed the impacts of environmental friendly land use after the comprehensive land improvement implementing. The results showed that:(1) the built environment-friendly land use evaluation system, status and level of the environment-friendly land use could be completely expressed.(2) agricultural land, construction land and unused land of environment-friendly evaluation index would be improved from 2008 to 2020, agricultural land use and environment-friendly composite index rose from 0.191 6 to 0.247 0, construction land use and environment-friendly composite index rose from 0.265 3 to 0.443 3, unused to using environmentally friendly composite index rose from 0.042 2 to 0.086 6;(3) the land use and environment-friendly comprehensive evaluation index would reach up to 0.776 8 from 2008 to 2020, 55.7% increase in degree. Thus, the comprehensive land improvement is to improve the state of regional land use and environment-friendly important way in accordance with sustainable land use and land a reasonable idea.
